I had read about this product with some doubts. Powdered peanut butter with few calories - it just doesn't ring true without ruining something from the original. Despite these doubts, I decided to sample a couple of jars. That was about it . . . after a couple of tries I was unable to finish the product. I have read recently that someone recommends adding a spoonful or two to your protein drink . . I have yet to try this.
